Theouter con tainer usually' has the: bottom and cover crimped to the sides so that itis' necessary'to destroy the containerif it is desired to remove the inner filtering unit, therebv'prohibiting replacement'of the latter and necessitating the throwing away ofthe'entireifilter. 1" A It is an object of the present invention to constructcontainers which" will'ghave aremovable end piece so that the inner filtering unit maybe removed and a. newone'supplied Without. destroying the container. This will enable the same container to be u sed indefi; nitely, resulting in a decreased cost in the price of the filter; V

The bolts 50 have wing nuts 56 which seat against the prongs 46 defining the slots 47 in the upper ring member 40. When the wing nuts 56 are tightened the flange 42 of the ring 40 will press the flange 26 of the cover 24 down onto the gasket 22 resting on the flange 18 of the container 10 and form a liquid tight connection.

If desired, the shanks 48 of the bolts 50 may have secured thereto in any suitable way the ring member 58, the purpose of which is to hold the bolts 50 rigid with the ring 28, although these additional rings 58 may be omitted if desired.

Referring to the s ecies of Figures 3 and 4, it will be seen that in place of the combined ring and bracket member 28 of Figures 1 and 2, I make use of a ring 60 having a plurality of loops 62 around its periphery and in which loops there is secured by means of a bolt or rivet 64, the eye 66 of an eye bolt 50. The shank 48 of this bolt enters suitable slots 47 defined by the prongs46, on the upper rin member 40' which isessentially the same as. t e corres onding ring member 40 in Figure 2, the di erence residing in the provision of an additional flange 70 which rests on the edge 72 of the cover 24, which in this instance is a flat sheet.

Instead of forming the flange 18 of Figure 2 directly on the container, I employ the separate annular member 76, which has the flange 18 integral therewith, and which member 1s permanently secured to the upper portion of the container.

In order to'replace the filtering unit 12 of either species, I the wing nuts 56 are unscrewed, which will release the ring members 40 or 40 and permit the removal of the covers 24 or 24, which in turn will allow access to the filtering unit 12 so that it may be removed and a new unit, inserted. After the new unit is inserted, the covers 24 or 24' are set in place, the rings 40 or 40 applied and the wing nuts 56 screwed onto the bolts which will clamp the connections in liquid tight relation to the container 10.

The flange. 18 of Figure 2, or the corresponding structure of Figure 4, need not necessarily be applied at the top of the container. The connection may be placed at the center in which case the cover will be cupshaped and fit well down over the upper portion of the filtering unit.

I claim:

1. In a container, a cover, a unitary sup-v porting ring and bracket for said container, and; means connected with said ring-bracket for permanently and rigidly securing said cover to said container.

2. In a container, a flange thereon, an integral supporting ring and bracket associated therewith the ring portion thereof abutting said flange, a flange-on said supporting ring, a cover resting on said container flange, a securing ring resting on said cover, a flange on said securing ring, and means extending between said ring flanges to hold said cover on said container.

3. The combination of claim 2, said means comprisin bolts and nuts, one of said flanges having po ygonal openings for the reception of a correspondingly shaped part of said bolts and the other flanges having slots for the reception of the ends of said bolts.

4. In a container, a cover, a unitary sup porting ring and bracket for said container, and means connected. with said ring-bracket for securing said cover to said container, said meanscomprising a holding member on said cover and connections between said ringbracket and member.

5. Ina container, a cover, aunitary supporting ring and bracket for said container, and means connected with said ring-bracket for securing said cover to said container, said means comprising a ring associated with said cover and bolts extending between said ringbracket and said cover ring.

6. In a container, a flange thereon, a ring for supporting said container at said flange, a cover and means associated with said cover and connected to said ring for holding said cover on said container, said ring also constituting a supporting bracket.

7 In a container, a flange thereon, a rin abutting said flange, a cover resting on sai flange, a ring .resting on said cover, and means extending between said rings for holdingsaid cover on said container, said rings having right angularly turned flanges for the reception of said means, one flange having polygonal openings and the other flange slots in which said means is received.

- 8. In a container, a right angularly turned annular flange on said container, a ring surrounding said container and abutting said flange, a mounting or supporting bracket formed integral with said ring, a flange on said ring extending away from the container,

a cover, a flange on said cover resting on said annular flange, a ring adapted to be positioned over said cover flange, a flange on said last named ring, and means for securing said rings together through their flanges.

In testimony whereof I affix my signature.
